What’s Driving the Replacement of Traditional Keys by RFID Keyfobs?

RFID Keyfobs is a booming industry, an industry that is getting closer and closer to our lives. As people are increasingly keen on pursuing not only practical but also beautiful life, RFID keyfobs are becoming more and more popular. Individuals or companies can customize unique keyfobs to show their quality of life and attitude towards life, as well as the company’s professional image.

What Is an RFID Keyfob?

RFID Keyfobs are essentially mini pendants that encapsulate various RFID chips of low frequency, high frequency or ultra-high frequency in keychains or beautiful shells of various shapes. Their shells are usually made of high temperature and corrosion resistant PVC or ABS materials, so they have the advantages of light weight, durability and easy to carry, which is very convenient for daily use. 

The front and back covers of high-quality RFID Keyfobs produced by professional manufacturers are sealed with ultrasonic welding to ensure excellent waterproof, dustproof and drop-proof performance, such as our factory.

How Does It Work?

Each RFID Keyfob has a smart brain – the RFID chip mentioned above. So when we hold the RFID Keyfobs close to the card reader installed in the access control system or down payment device, the electromagnetic waves emitted by the card reader will wake up its dormant brain, activate the chip, and then send the stored data to the system for verification. 

All of this can be done with just a 0-10 cm approach. The entire process takes less than a second: fast, silent, efficient, and secure.

Why Are RFID Keyfobs Becoming More Popular?

Let’s briefly compare traditional RFID cards and RFID Keyfobs:

When carrying multiple RFID cards with different frequency bands, card interference often occurs, leading to reading failures. The independent identification capability of RFID Keyfobs solves this issue effectively.

Typical Application Scenarios of RFID Keyfobs

This high-performance, portable device is widely used across many sectors:

• Access control and attendance systems (offices, campuses, factories)
